The modular flexibility of the E-Series—with three disk drive/controller shelves, multiple drive types, and a complete selection of interfaces—enables custom configurations optimized and able to scale as needed. The maximum storage density of the E5500 reduces rack space by up to 60%, power use by up to 40%, and cooling requirements by up to 39%.

Backed by NetApp's 20+ years of storage-development experience and more than 650,000 systems in the field, the E5500 provides a field-proven architecture with high reliability and 99.999% availability.
